A pressure detection method is characterized in that: the method comprises the following steps:
Arranging a plurality of gaskets, arranging a passive radio frequency tag in the gaskets, and arranging a screw hole in the middle of the gaskets for matching with a bolt to be installed;
setting an FRID reader-writer, and setting the FRID reader-writer within the range of 10X10 meters;
The method comprises the steps that a server is arranged, the server is communicated with an FRID reader-writer, and position information and pressure information of bolts corresponding to gaskets are stored;
And the wireless receiving device is communicated with the server and transmits the position of the wireless receiving device into the server through a GPS.
Further: the information of the gasket received by the server comprises a pressure value, the position information of the bolt and the number of the bolt, and the server program establishes a bolt distribution map according to the information of the gasket.
Further: the server program firstly establishes a primary map of the FRID reader-writer, and each marked FRID reader-writer enters a secondary map of a gasket corresponding to the FRID reader-writer after clicking.
further: and the server program judges the pressure value, if the pressure value is smaller than the set value, abnormal identification is carried out on the map, the wireless receiving device closest to the abnormal identification bolt is calculated according to the received position information of the wireless receiving device, and alarm information is sent to the wireless receiving device.
Further: the alarm information comprises a first-level map of the FRID reader-writer and a second-level map of a gasket which is clicked to enter the FRID reader-writer.
Further: the FRID reader-writer comprises a signal receiving end and a signal transmitting end, every two FRID reader-writers can be connected in a point-to-point communication mode, when the position where the FRID reader-writer is located is weak and cannot be directly connected with a server, an invitation is sent to the adjacent FRID reader-writer, the adjacent FRID reader-writer with strong signals serves as a relay to send signals to the server, and the server records the transmission path of the signals.
compared with the prior art, the invention has the beneficial effects that:
the pressure is detected by adopting the gasket with the built-in passive radio frequency tag, information is read by the FRID reader-writer and is stored in the server, and the bolt with an abnormal pressure value is conveniently searched by connecting the pressure detection device with the wireless receiving device, so that the problem can be timely checked, and the labor is saved. The error rate is reduced. The safety of the equipment is ensured.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, taking the bolt of the rail as an example: a method of pressure detection, comprising: each bolt needing to be overhauled is sleeved with a gasket 1, a passive radio frequency tag is arranged in each gasket, and a screw hole is formed in the middle of each gasket and used for being matched with the bolt needing to be installed; an FRID reader-writer 2 is arranged in the range of 10X10 meters and receives the information of the passive radio frequency tags in the administrative area. For the rail, due to the long distance, a plurality of servers 3 can be provided, each server has a jurisdiction range, communicates with the rfid reader/writer 2, and stores position information and pressure information of the bolt corresponding to each pad. And the wireless receiving device 4 is adopted to communicate with the server and transmit the position of the wireless receiving device into the server through the GPS. After the wireless receiving device enters the jurisdiction range of the server, the wireless receiving device automatically establishes contact with the server, and the position is sent to the server through GPS positioning after a certain time interval.
The information of the gasket received by the server comprises a pressure value, the position information of the bolt and the number of the bolt, and the server program establishes a bolt distribution map according to the information of the gasket. The server program firstly establishes a primary map of the FRID reader-writer, and each marked FRID reader-writer enters a secondary map of a gasket corresponding to the FRID reader-writer after clicking.
and the server program judges according to the received pressure value, if the pressure value is smaller than a set value, abnormal identification is carried out on the map, the identification comprises a corresponding FRID reader-writer in the primary map and the gasket position in the secondary map, a wireless receiving device closest to the abnormal identification bolt is calculated according to the received position information of the wireless receiving device, and alarm information is sent to the wireless receiving device.
The alarm information comprises a first-level map of the FRID reader-writer and a second-level map of a gasket which is clicked to enter the FRID reader-writer, and the first-level map and the second-level map are sent to the wireless receiving device. The map can be created according to the running direction of the rail and the actual distribution of the bolts in the rail.
Each FRID reader-writer comprises a signal receiving end and a signal transmitting end, each two FRID reader-writers can be connected in a point-to-point communication mode, when the position of the FRID reader-writer at a certain position is weak and cannot be directly connected with a server, an invitation is sent to the adjacent FRID reader-writer, the adjacent FRID reader-writer with strong signals serves as a relay to send signals to the server, the server records the transmission path of the signals, and the situation that the certain FRID reader-writer at the position with weak signals cannot transmit the signals to the server is prevented.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
